Sizing
Determining the correct ring can be a fickle business. Here’s what to do and how to do it!
Come visit Millie: The most accurate method is to have your fingers measured at a jewelery store. Come visit one of our stores in Fitzroy, London or New York and our gorgeous team will help you find your perfect ring size! If you can't make it to one of our stores, any local jeweller will offer complimentary sizing.
Measure an Existing Ring: If you have a ring that fits well, you can measure its internal diameter. Use a ruler to measure the distance across the inside of the ring in millimetres (see reference pic below). Make sure the middle of the ring is on the edge of the ruler, then use the chart below to match the diameter to your ring size. Half a millimetre can be a change in size, so be careful. If you're in doubt, email us a photo of a ring that fits you well on a ruler and we can help.
